Lorene Bible believes viewers of the upcoming HLN Original Series "Hell in the Heartland: What Happened to Ashley and Lauria?" should come away with a sense of the pain and frustration she has suffered since her daughter disappeared almost 20 years ago.

Outrage was the most prominent reaction the mother of Lauria Bible heard voiced by an audience of 3,000 people who watched a 10-minute clip of the series about the Freeman-Bible murders case at a special preview she attended recently in a theater in New York City.

Bible and her niece, Lisa Brodrick, were introduced to the crowd after the showing.

"The writer, the producer and associate producer have done a good job," Bible told the Globe last week. "It's just well put together."

She said viewers came away convinced that the Craig County Sheriff's Department and the Oklahoma State Bureau of Investigations bungled the initial investigation of the murders of Danny and Kathy Freeman and the abduction and presumed slayings of their daughter, Ashley, and her friend, Lauria, two 16-year-old girls.

She expects that sense of outrage to resonate all the more powerfully when the series airs in its entirety on four consecutive Sundays beginning at 8 p.m. Sunday, June 2, on the HLN (Headline News) channel.

The documentary series is based on the research of crime author Jax Miller and former police investigator Sarah Cailean.

Penguin Random House plans to publish Miller's book about the case, "By the Dawn's Early Light," in the summer of 2020.

According to a series overview posted on CNN Press Room, the series premiere is titled "The Fire" and focuses on the night of the crime, Dec. 30, 1999, when the Freeman family's trailer home near Welch, Oklahoma, burned to the ground and the Freeman parents' bodies were discovered among the home's ruins.

In the second episode, "The Suspects," Miller and Cailean explore the back story of the Freemans' conflict with the Craig County Sheriff's Department following a deputy's fatal shooting of their son, Shane, a year before the murders.

Early leads in the case are detailed and various suspects revealed.

The third part -- "The Dig" -- explores the sidetracking of the investigation when serial killer Jeremy Jones "confessed" to his involvement, leading to a fruitless search near Galena, Kansas. Jones' eventual recanting of his confession leaves the investigation stalled once again.

In the final part -- "The Arrest" -- the series looks at the reopening of the case with the election of new sheriff and the rediscovery of neglected evidence that helps break the case open and lead to the arrest of a 67-year-old suspect, Ronnie Dean Busick.

The former Kansas inmate is the lone surviving suspect in the case. He is believed to have acted in concert with Warren "Phil" Welch II and David A. Pennington in committing the crimes.

But Welch, who was 54 at the time of the murders, died in 2007, and Pennington, who was 41, died in 2015 at the age of 57. Neither of them were ever charged.

The first two parts of the series will have aired by the time Busick is scheduled to have a preliminary hearing June 14 in Craig County District Court. He faces four counts of first-degree murder, two counts of kidnapping and a single count of arson.

Investigators now believe the girls were held and sexually assaulted inside Welch's home in Picher following the shooting of the Freeman parents and the torching of their home.

Lorene Bible hopes the HLN series will "bring new light to the girls' disappearance."

"Hopefully, it will bring more people forward who know something because people are going to be outraged," she told the Globe.
